[ros-kernel] NtQuerySection dubts

[Mike Nordell]

Hartmut Birr provided a large part of the VirtualQuery problem a few days
ago, making it work for a particular kind of requests. However, there are
parts missing.

To make a long story short, the AllocationBase seems again wrong on ROS and
here's the source (to be added to regressions?). Comparing NT and ROS output
it's quite obvious. As I myself again isn't too familiar with the area...

#include <windows.h>

int main()
{
    LPCVOID p = (LPCVOID)0x571100; // intentionally outside .exe
    MEMORY_BASIC_INFORMATION mbi;
    DWORD dwRet = VirtualQuery(p, &mbi, sizeof(mbi));
    printf("dwRet       = 0x%#x\n", dwRet);
    printf("MEMORY_BASIC_INFORMATION {\n");
    printf("BaseAddress      :  0x%#x\n", mbi.BaseAddress);
    printf("AllocationBase   :  0x%#x\n", mbi.AllocationBase);
    printf("AllocationProtect:  0x%#x\n", mbi.AllocationProtect);
    printf("RegionSize       :  0x%#x\n", mbi.RegionSize);
    printf("State            :  0x%#x\n", mbi.State);
    printf("Protect          :  0x%#x\n", mbi.Protect);
    printf("Type             :  0x%#x\n", mbi.Type);
    return 0;
}


Output from NT5:
0x571000, 0, 0, 0x77a0f000, 0x10000, 1, 0
>From ROS:
0x571000, 0x51f000, 0x40, 0xbe000, 0x1000, 0x40, 0x20000

Can anyone verify these findings?
